Be it known that I, HARRY W. SMITH, a citizen oi the United States, end e resident oi North Grafton, in the county of `Worcester end State of Massachusetts, lieve invented an Improvement, in Weit -Replenishing Looms, of which the following description,

`inthat patent in connection with the accompanying drawings, is e specification, like letters on the drewnig-s representing like parte.

y This invention 1s en improvement on the class of looms described in VUnited States Patent No. 665,559, dated Jennery 8, 1901.

` To enableany formorcharecterof filling-4 carrier togbe used in a filling-re lenishingi loom, I have provided a feeler and slliuttle, the one with emagnetic and `the other lanlagend preferebly mount `udpon me the feeler, which is supported in a yiel b manner, as set forth in said patent, a cali-v bratinggage, which in the working yof the anrordinary loom with my y addedtoenable my invention `to bevunder- TOC ox eing repre- Fig. 2 is c top'plan view* oftheleftdiend end ofthe loom .shown in Fig. 1i` Fig. 3 isha detail showing theceli- A pering-,gage in contact with thefilling.

The loom-frame 2, the breast -beam 3, the lay 4, having at its ends suitable shuttleboxes, one ol which is slotted at` its bottom for thedischarge of the iilling-carrier'b, supplied with filling b, the binder 9, the fillingfork 13, carried by the slide 14, the knock-ofi lever 15, pivoted at 16 and moved by the slide 14 whenever the lling breaks to release the shipper-handle 17 from its usual holdingnotch and stop the loom, the connecting-rods 18 for moving the lay, the selfthreajling shuttle A, the rock-shaft 21, having an upwardly-extending arm 22, the, slide-bar f, having pivoted upon its inner end an overbalanced lever fto thereby keep its outer end nearest the breastbeam normally in an elevated position, as shown in the drawings, thc leverf but partially shown, it having its upper end forked and operated once for each pick by a suitable cam on the usual camshaft, the illing.-l changing means represented by the"I pusher h, shown in dotted lines mounted on a stud h and deriving its movement from the rock-shaft 21 Whenever the slide-barf is moved backwardly in its guide,are/ common to United States Patents a side view No. 529,940, dated November 27, 1R94, and

No. 633,976, -dated September 26, 1899, and said parts, being fully described in said-pat ents need not be herein further specifically described. I will also state that the wire coil 31, connected with and in. a suitable circuit preferably with asource of electric energv, such-for instance, as a dynamo-said coil surrounding and guiding a feeler b, making of it a ymagnet. which is maintained in normal balanced position by said coil, is well understood in the operation of solenoids, the arm 34, extended from the rockshaft .'35 and resting on the inner end of the feeler, and the arm 36 and finger 37, overlying the inner end of the overbalanced lever f, are'and maybe all as fully provided forin said Patent No. 665,559, and instead of the wire coil shown,which makes of the feeler a magnet, l may" use the equivalent means shown in said patent to normally balancea permanent magnet.'

l will now describe the particular novel features which constitute the invention to be hereinafter claimed. l have provided the side wall of the shuttle A at or near the usual 'hole b4 therein for the feeler with a body, as b5, represented as a metal plate, and to coact with this body I employ a feeler, and the body on the shuttle and the body of the feeler are one of magnetic anrl the other of magnetized metal. Preferably the shuttle carries the magnetic body and the feeler is a magnet. l have connected adjustably lto the inner lend of the feeler b a calibratinggage b, the length of which may be adapted to the thickness of the filling 52X, wound on the paper or other cop-tube d, upon which the filling was spun on a mule or other suitable spindle. The front wall l() of the shuttleboxgrbelfl in place as at 10X, is cut away to expose the body b5 to the action of the mag netized feeler.

In the operation ofthe loom at every other movement of the lay toward the fell the shuttle-box'opposite the magnetized feeler will containJ shuttle having filling, and as the lay approaches the fell the filling will strike the end etl the calibratingage and ush the magnetized feeler outward y or to t e right, viewing Fifr. 1, under the arnn and as the lay moves backwardly from the tell the Wire coil or other equivalent will restore the mawnetized feeler to its 'normal position. 0 lon as a proper amount of filling is present in tie shuttle the arm 34 will be sustained by the feeler and the pusher. zfwill not act. lie-53 the filling is unwound in weaving its diameter gradually decreases, letting the calibrat-- ing-gage enter farther into the shuttle, and finallyn when the lilling is suihciently er@ hausted or exhausted to a predetermined point the end of the feeler is permitted to contact (see Fig. 4) with the body b5 ci the shuttle, and as the lay is moved backwardly from the fell the body b5 adhering to the magnetized feeler will draw the latter'with it from under the arm 34, which done vthe rock-shaft 35 will immediately turn, due to the weightof the fing'er 37, causin said linger to depress the normally elevate( inner end of the oveiibalanced lever f, so that the fork at the up er end of the lever f' will engage said overli slide-bar f2 with it, will through the arm 22 turn the rock-shaft 21 `and actuate, in accordance with the'patents hereinbefore referred to, the pusher h to insert Fresh 'filling into the shuttle, said shuttle being, it will be understood, then at that end of the lay immediately under the usual hopper containing the su ply of filling-carriers.

nstead of actuating a pusher, such'as hereinbefore referred to, to change the filling when the feeler-magnet is put into itsv ab normal position, as stated, said freeler-magnet mayin its abnormal position be made .to control the startin r of filling-chan ing means such as provided or in United tetes Pat# ents'No. 600,490, March 8, 1898, or No. 661,752, November 13, 1900, wherein pr 1- vision is madeI for changing a shuttle from which filling haswbeen exhausted and suppl ing for it a shuttle containing a supply of filling properly threaded, the change being effected after the indication showing that th'e filling has been exhaused to a predetermined point by a change 'of position oliy Sln1ttlc oxes as therein rovided for,

YIO

By the term ody" as applied the de A vice attached to the shuttle intend'to cover a piece of metal of any shape adapted to be i 3o .with the shuttle as ofmagnetic material and the feeler l) as a magi et; but this invention ,would not be departed. from should the bodv b5 be made 'a magnet and the feeler b be of` magnetic material, yet this would not produce as goed results as in the first-described plan.

In the claims I shall refer to the shuttle as having a body, and lshall refer to the feeler as also having a body, and either of these bodies may be of magnetizeih the other being of magnetic, material. As shown, the shuttle is provided With an open top and bottom. .Izlaving described my invention, what I claim, and desire to secure by Letters Patont, is-
